  1. Can this be stated in other words, "Electromagnetic waves are only transverse and gravitational waves are both longitudinal and transverse" ?

  2. That there are things that are too dark or too small to see s pretty obvious. I don't know if that is what you were referring to. Perhaps what is less obvious is that there are things we cannot see because the light from them hasn't reached us yet. And there are things that we will never be able to see because the expansion of the universe means the light from them will never reach us. "Hidden in time" is poetic, but not very meaningful. What "t coordinate" are you talking about? And why wouldn't it correspond to distance? So what exactly is the reason we can't o

  4. Kinetic and gravitational time dilation. Mass-energy equivalence. Bending of light due to gravity. Neutron stars and Black Holes. Gravitational waves. Frame dragging. ETC. All have been observed and verified. Yet we still get people coming here claiming A Einstein was wrong .

  5. Thanks. I found some interesting info* about the Biefeld-Brown Effect and Corona Wind Phenomena that I'll try to read later. Probably not connected to the idea above, but interesting. I've seen videoclips of small levitating devices** but not bothered to check the basic principles behind it. Back to the original problem Can we get a simplified view of just the parameters involved in the calculation you need help with? The original sketch give an idea but I have trouble seeing which current(s) you want to take into account. *) Referenced paper(s) https://en.wikipedia.

  6. A lot of people view this as a "one or the other" situation. Personally I do not. The impeachment process was developed for exactly the kind of behavior Trump has exhibited. IMO it would have been of dereliction of responsibility to simply 'pass the buck' to the voters. The reason I say it is not a "one or the other" situation is because we can have an impeachment AND let the voters voice their opinion in November, either for/against Trump or for/against the Republican party. I was never under any illusion that Trump would be removed from office, and I understand there was risk to th

  7. The vote to allow witnesses and testimony was defeated 51 to 49. Romney and Collins were the only two Republicans to vote yes. No Democrats defected.

  8. Yes it involves the most efficient arrangement due to gravitational force. For example take some irregular planetoid of low mass. If it's mass increases. That planetoid will gradually become more spherical. Recall the formula for gravitational force and then think of the implications of a centre of mass.

  9. The theory of relativity claims that all clocks regardless of their design and principle of operation, slowdown their ticks in the following cases: - during its movement, according to the formula T = To / (1- (v / c) ^2)^0,5 - as gravity increases. It turns out that such a slowdown of the clock ticks, called time dilation, is true only for light clocks, which include atomic clocks, and does not apply to all clocks. This slowing down of the clock ticks is therefore only a technical feature of light clocks, and not a dilation of time as such. For example, the pendulum clock will not
